Gotta be honest, Saitama is a pretty terrible hero.
He's great at disposing of villains, but he spends entirely too much time standing around while they kill people, or accidentally causes massive collateral damage like this.
It isn't so boring if you've got other things to occupy your time and don't just live for combat.
... Speaking from my experience in every Elder Scrolls game... where sometimes the things that explode in one hit drop neat loot, and I can always explore the dungeons and the towns and do quests and suchlike without having to worry about accidentally dying to a rat... though the endless respawning guards on the hunt for criminal scum are a nuisance. ^_^
